A plan is typically any procedure used to achieve an objective. It is a set of intended actions, through which one expects to achieve a goal. Plans can be formal or informal:
- Structured and formal plans, used by multiple people, are more likely to occur in projects, diplomacy, careers, economic development, military campaigns, combat, or in the conduct of other business.
- Informal or ad-hoc plans are created by individuals in all of their pursuits.
A lack of planning in any discipline may lead to a misallocation of resources, misunderstandings, or irrelevant sections added to Wikipedia articles such as this one.
In the field of architecture an architectural plan it is a design and planning for a building, and can contain architectural drawings, specifications of the design, calculations, time planning of the building process, and other documentation.
Architectural drawings are used by architects and others for a number of purposes: to develop a design idea into a coherent proposal, to communicate ideas and concepts, to convince clients of the merits of a design, to enable a building contractor to construct it, as a record of the completed work, and to make a record of a building that already exists.
Architectural drawings are made according to a set of conventions, which include particular views (floor plan, section etc.), sheet sizes, units of measurement and scales, annotation and cross referencing. Conventionally, drawings were made in ink on paper or a similar material, and any copies required had to be laboriously made by hand. The twentieth century saw a shift to drawing on tracing paper, so that mechanical copies could be run off efficiently.
